OH dear. Sienna Miller seems to have forgotten her table manners on a posh lunch date with boyfriend Jamie Burke.

The Factory Girl star guzzled glasses of wine, put her feet on the table and chain-smoked throughout the meal at Hollywood's swanky Chateau Marmont. Worse was to come - when the 25-year-old actress began picking her nose. For "afters" she and Jamie shared a sloppy kiss and cuddle. And she didn't even wash her hands first.
